ARTHUR R. HAVEN'ER, OF 'WAYLAND, MASSACHUSETTS, ASSIGNOR TO JUDSON L. THOMSON MFG 00., A CORPORATION OF MASSACHUSETTS.

i I Specification of LettersPatenta Patented Sept. e, 1918.

Application filed March 4, 1918. Serial myazoaea To all whom it may concern: I

Be it known that I, ARTHUR R. HAVENER,

a citizen of the United States, residing at Wayland, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Hoppers, of

' which the following is a specification.

. one by one to particularly adapted 1 ..around by the picker platewould stick to.

the inclined upper This invention relates to a hopper separating articles from a mass of the same contained in said hopper and feeding them a raceway. The hopper is articles of the form known as rivet caps and to feed the particular which has a recess in one first, in the face of said picker plate and sometimes cause trouble and applicant has conceived the idea of having the inclined upper face, of the picker plate ad acent. the periphery thereof conveXly curved in cross sectlon and by such formation of the picker plate the difficulty ofthe rivet caps sticking to the surfaceof the plate is overcome.

' picker plate in case vof any obstruction to the rotation still while themechanism which drives it H 47 i see Fig.2. This convexly curved portion is preferably adj acentfto the periphery of the ,,.Figure 1 is asideelevation Another object of the invention is to com .struct the casing of the hopper and the picker plate thereof insuch a manner that theymay be readily detached from the driving shaft and furthermore to drive the picker plate frictionally so that ofthe pickerplate it will come too. standcontinues to rotate.

To these ends the invention consists in the combination and arrangement of parts set forth in the following'specification and particularly pointed out, in the Referring to the drawings for to feed disk-shaped form of rivet cap face thereof and an inwardly pro3ecting annular flange surthe inclined upper face of pin 3 is inclined and claims thereof.

ofjIa hopper embodying my invention and the mechanism by which t is driven.

Fig. 3 is a sectional elevation taken on line 3-3 of Fig. 2.

Like numerals refer to like parts throughout the several views of the drawings. a

6 is the picker plate and 7 the rotary shaft by which the picker plate is driven. The shaft 7 is journaled to rotate in a bracket 8 and has a rotary motion imparted thereto by a worm gear 9 which is driven by a worm 10 to whlch a rotary motion is imparted by" a pulley 11.

The picker plate 6 is frictionally driven by a driving member 12 which consists of a disk 13 and a hub 14,'the hub being fastened by a pin 15 to the shaft 7. A collar '16, preferably of fiber, is interposed between the .disk 13 and the picker plate 6. Said picker plate 6 is loosely mountedupon the shaft 7 and is yieldingly held against the collar 16 by pins17 which are located in holes 18 provided in a collar 19. 'Thepins 17 arepressed against the picker plate 6 by springs 20 which hear at one end against the pins 17 and at the other end against a cross- 21, which fastens the collar 19 to the shaft 7. 2' l The collar 19 is located upon the shaft 7 on the opposite side of the picker plate from that upon which the driving member '12 is located and is attached to said shaft by pushing the collar onto the end of the shaft,

tion of the L-Shaped slots 22. When the come into alinement with the transverse'portions of said slots the collar is turned until the pin 21 bottoms in said transverse portio'ns;

The upper facel23f of the picker plate 6 has an annular portion 2 1 which is conveXly curved inicrosssection,

, picker plate 6 and project from said convexl 1 d rat s .2???) Eerie s P120" Fig. 2 is a sectional elevation of the same.

of. projections '25, preferably "in In the drawings, 5 is the hopper casing,

i with the cross-pin 21 in the longitudinal porwill slide off of theconvexly curved annu lar portion of the upper face ,of said picker, 1 plate and back into the mass, of, rivet caps I at the bottomof the ,hopper casing, as it a said hopper casing is detachably ,fastenedto a stationary support consisting of a bracket 31' by means of screws 32. The outer end of the bracket 31 islocated at ,one side of the casing 5 and extends across thepicken plate .6 outside the periphery thereof, so

that the hopper casing 5 maybe removed and also so that the picker plate may be removed vfrom the shaft 7 with very little difliculty, V

Thegeneral operation of the hopper and its driving mechanism, hereinbefore specifically describecLis as follows: The rivetcaps areplaced in the hopper casing 5 and are locatedin mass in the lower portion of said driven by the shaft 7 and driving, member 12 through contactwith the friction collar.

1G. The shaft 7 is rotated by meaus of the worm gear 9, worm 10 and pulley 11, The

and its. pins 25 and delivered to the race; way 30 :in the manner set; forth in Let ters Patent It will be seen that any rivet cap which isnot caught upon one,,of the pins, is carried up ,on the pic ker plate it only has a very slight portion of its surface in contact withysajd convexly curved portion of the upper .face of the picker plate and, therefore, will not stick .to it, as is often found to be the ,casewhere the inclined up} per face of the picker plate is flat, especially throughout that portion, ,of said upper face fronrwhich the pins 25 project.

I claim: I, l H 1.'A hopperfor feedingzarticles having, in combination, a casing, and a cylindrical picker plate rotatably mountedin said cas ing and having .an inclined, upper face, an,

annular portion of said upper face extending ent relyiaround,sald picker plate and behopper. The picker plate is frictionally rivet caps ,aretaken from thea mass inthe: bottom of, the casing 5 bythe picker plate 6 ing convexly curved in cross sectionthrough out. its entlre length.
